BSOD error 0x0000000A occurs a lot recently !

It's a long story, but I will try to make it as short as possible.

First of all, that's not the only BSOD I get, I get a lot of different other BSODs, however this one shows up the most, and I suspect it's because of my RAMs, as it only occurs when I load stuff like games or so !
The second thing is that, the computer runs normally, until this thing shows up, then it begins to run slowly, specially at start-up, I changed my power supply today since I got a new VGA card that required a fresh PSU, and my old one was worn already, so it's pretty much not the PSU here.
And no, it's not the VGA, because these BSODs used to appear even before I got the VGA, anyways it disappeared for a while, that while when I deactivated the O.C. cores of my Processor, I am confused but I guess it's the RAM, because it even sometimes occur when I'm on the usual cores of Processor.

Any advices ? N.B. I see the word " MEMORY_MANAGEMENT " a lot in these BSODs.

Oh another N.B. I have 2 x 2GB KINGSTON RAMs but I don't quite remember the model number.
If it's about the RAMs as I assumed, how can I find out which one is malfunctioning ?

Thank you !
